Chris Lattner d7dc1ecd42 The system ranlib on darwin occasionally adds two extra newlines to the
end of files, breaking the CFE build.  As a gross hack around this,
ignore any trailing garbage on bytecode files.  Thanks to Brian for digging
in and identifying the problem.

Reid Spencer 7c16caa336 Changes For Bug 352

Reid Spencer 191aa30ac1 Bytecode Reader Cleanup:
- provide the correct conversion for ModuleBlockID in read_block (a potential
  bug but not actually exploited because reading module block ids doesn't
  use read_block).
- install support for handleTypeList handler
- install support for handleDependentLibrary handler
- install support for handleTargetTriple handler
- clean up comments, output strings,
- ensure that processing function arguments doesn't SIGSEGV if one of the
  arguments is a null pointer (yeah, it happened .. weird)
- prepare for version 5 bytecode by documenting what will change.

Chris Lattner 74635dc879 Fix a serious bug in the double constant reader. In particular, because
(At[3] << 24) is an int type and it is being coerced to uint64_t, it was
getting sign extended, causing us to get FFFFFFFFxxxxxxxx constants all of
the time.

Reid Spencer b2bdb943b5 bug 263:
- encode/decode target triple and dependent libraries
bug 401:
- fix encoding/decoding of FP values to be little-endian only
bug 402:
- initial (compatible) cut at 24-bit types instead of 32-bit
- reduce size of block headers by 50%
Other:
- cleanup Writer by consolidating to one compilation unit, rem. other files
- use a std::vector instead of std::deque so the buffer can be allocated
  in multiples of 64KByte chunks rather than in multiples of some smaller
  (default) number.

2004-07-13 07:37:43 +00:00
Reid Spencer 194c576efc Various cleanups:
- Remove tabs
- Standardize use of space around ( and ).
- Consolidate the ConstantPlaceHolder class
- Rename two methods to be more meaningful (ParseType, ParseTypes)
- Correct indentation of blocks
- Add documentation
- Convert input dependent asserts to error(...) so it throws instead.
Provide placeholder implementations of read_float and read_double that
still read in platform-specific endianess. When I figure out how to do
this without knowing the endianess of the platform, it will get implemented
correctly.

Reid Spencer f3905c8511 Error Handling Cleanup:
- get rid of PARSE_ERROR macro
- add error(std::string) function
- use error(std::string) for all errors
- make input dependent asserts call error(std::string) instead
- ensure asserts are only for logic bugs, not input discrepancies.

Reid Spencer 6a218134e3 Fix a backwards compatibility bug found by Tanya. In version 1.2, the
global type plane starts with a length and the TypeTyID value to identify
the type plane has having type definitions. This doesn't happen in 1.3
because the types are read from a known position in the file. However, the
TypeTyID must be read in (and ignored) if its a 1.2 bytecode file.

Reid Spencer 02b6708e01 Finalize bytecode dumping. The "handleFinish" method was getting called
too soon so the function data was not getting dumped (it was generated
after the call handleFinish). Also cleaned up the output format for
proper indentation.

Reid Spencer bc70f74825 - Don't use macros to call the BytecodeHandler
- Don't use PARSE_ERROR macro unnecessarily (for simple strings)
- Add comments before each function
- Convert for bug 122 (Type != Value)
- Handle new value range on Type::PrimitiveTypeId enumeration by augmenting
  the reader with a new read_typeid method and sanitizeTypeId method.
- Remove BytecodeHandler's default method implementations to header file.

Reid Spencer 284b7c7174 MAJOR REWRITE.
- stop passing Buf/BufEnd to every function (now member vars)
- internalize things that used to be in a header file that no one else
  included/needed.
- Remove defunct BCR_TRACE lines
- Standardize error handling with the PARSE_ERROR macro.
- Integrate ConstantReader.cpp and InstructionReader.cpp and reorgnize
  the definition order so that gcc has a chance at optimizing this module
- Standardize case and style of method names.
- Eliminate unneeded header files
- Prepare for Type != Value (bug122) change by splitting Types into their
  own data structures.
- Implement the BytecodeHandler interface calls.
- Provide default implementation of BytecodeHandler interface.

Chris Lattner 15701e84d1 Implement support for a new LLVM 1.3 bytecode format, which uses uint's
to index into structure types and allows arbitrary 32- and 64-bit integer
types to index into sequential types.

LLVM 1.0+.

intelligently.

llvm-svn: 10918
2004-01-18 22:35:34 +00:00
Chris Lattner e104d88f83 Add support for reading bytecode files with compactiontables for bytecode files.
This shrinks the bytecode file for 176.gcc by about 200K (10%), and 254.gap by
about 167K, a 25% reduction.  There is still a lot of room for improvement in
the encoding of the compaction table.

Chris Lattner 677af4a1cb Bytecode format for LLVM 1.2 no longer explicitly encodes zeros in primitive
type planes.  This saves about 5k on 176.gcc, and is needed for a subsequent
patch of mine I'm working on.

2004-01-17 23:25:43 +00:00
Chris Lattner e2f6317436 Allow bytecode files to refer directly to global values as constants, instead
of forcing them to go through ConstantPointerRef's.  This allows bytecode
files to mirror .ll files, allows more efficient encoding, and makes it easier
to eventually eliminate CPR's.

2004-01-15 17:55:01 +00:00
Chris Lattner faaf32db19 Change all of the bytecode reader primitives to throw exceptions instead of
returning error codes.  Because they don't return an error code, they can
return the value read, which simplifies the code and makes the reader more
efficient (yaay!).

Also eliminate the special case code for little endian machines.

llvm-svn: 10871
2004-01-15 06:13:09 +00:00
Chris Lattner 394afe0f90 Version 1.2 now supports encoding strings as a special case, to avoid having
to emit all of those sbyte constants.

2003-12-30 07:55:21 +00:00
Chris Lattner d9cf9b30eb Emit & read more compressed bytecode by not emitting a bytecodeblock for
each basic block in function.  Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions.  This
saves a fairly substantial chunk of bytecode space.  In stripped, sample
cases, for example, we get this reduction in size:

197.parser: 163036 -> 137180:  18.8% reduction
254.gap   : 844936 -> 689392:  22.6%
255.vortex: 621724 -> 528444:  17.7%

...

Not bad for something this simple.  :)  Note that this doesn't require a new
bytecode version number at all, though version 1.1 should not need to support
the old format.
